I am working on vectors in trig. Can you please help me solve the two questions in this problem?

1). what force should the weaker student apply to his rope so that the keg of socks heads due east?

2.) What resultant forces is applied to the Keg?

Two drunken college students have filled an empty beer keg with rocks and tied ropes to it in order to drag it down the street in the middle of the night. The stronger of the two students pulls with a force of 100 pounds at a heading of N77 E and the other pulls at a heading of S68 E. What force should the weaker student apply to his rope so that the keg of rocks heads due east? What resultant force is applied to the keg? Round your answer to the nearest pound.
